PURPOSE:To increase the life of an X-ray production source by producing X-rays after plasmas are produced by introducing a gas used as a material for the plasmas into a capillary from outside an insulator which has the capillary. CONSTITUTION:An insulator 1' having a capillary 2 is prepared...

OBSERVERS who use Wimshurst machines should remember that part of their difficulty in obtaining X-rays with a steady current and low vacuum may lie in a peculiarity of the machine itself, viz. that it will not work well when short-circuited. Machines with permanently charged armatures do not ...
X-ray analyzing system for x-ray scattering analysis An X-ray analyzing system for x-ray scattering analysis comprising an x-ray source for generating a beam of x-rays propagating along a transmission axis (3), at least one hybrid slit (5b) with an aperture which defines the shape of the...
The production of X-rays can be summarized as the following sequence of events: 1.The filament is electrically heated and a cloud of electrons is produced around the filament. 2.The high-voltage (potential difference) across the tube accelerates the electrons at very high speed towards the anod...
The support comprises a chamber (12) that contains the bearing and a joint (26) that insulates the bearing from volume of production of the X-rays. The chamber equips a reclosable opening (22) emerging outside of the enclosure. An independent claim is also included for a method for ...

ACCORDING to recent work, X-ray-induced chromatid breaks in Tradescantia microspores are due to the simultaneous occurrence of about seventeen ionizations concentrated within the narrow section of a chromatid. Such clusters of ionizations can be produced by electrons with small kinetic energy, that ...
